VENTILATING-SCREEN FOR WINDOWS.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed November 18, 1916. Serial No. 131,982.

To all whom it may concern:

Be it known that 1, Louis N. Moss, a citizen of the United States, and a resident of the borough of Manhattan, city, county and State of New York,have invented'certain new and useful Improvements in Ventilating-Screens for Windows, of which the following is a specification.

My improvements relate to the class of window screens set forth in Letters Patent No. 1,094,917, issued to me April 28, 1914:, designed primarily to be so positioned as to screen an opening made by raising the lower sash of a window for ventilating purcally so as to slide one upon the other, in

combination with means for securing them in extension with relation to each other, and for supporting the unitary screen thus formed in proper relation to the window so as to afford means of ventilation while obstructing observation through an open space formed by raising the lower sash of the window, all as hereinafter fully described and claimed specifically.

In the accompanying drawings,

Figure 1, is an isometrical perspective of component parts of my new ventilating window screen extended in relative positions for use;

Fig. 2, is an isometrical perspective of the parts of the device arranged in compact relationship for storage or transportation;

Fig. 3, is a transverse sectional elevation taken through the middle panel of the screen, the latter being shown as supported in position on a window frame;

Fig. 4, is a similar view taken through an end panel of the screen.

The main object of my invention being the production of a standardized device adaptable to windows of various sizes and dimensions, I make my screen in a plurality of sections or panels, preferably three, as shown in the drawings, consisting of a medial or basic panel A, and the auxiliary panels A, A mounted slidably on said middle panel A,.which forms the connecting link between the others.

The panels A, A, A are preferably of rectangular parallelogrammatic form, and of the same size, so that when not desiredfor use, or in packing for transportation or. storage, they may be arranged in neat, compact alinement as shown in Fig. 2, thereby reducing the space occupied to the minimum.

The panels A, A, A preferably consist each of a frame a, in which is mounted a plate or sheet oftranslucent material a, of any desired character, opalescent or stained glass being a desirable medium for obstructing vision while admitting of the passage of modulated light. Plates or sheets a, of opaque material, or even of transparent material, may be substituted for the translucent material if desired, but the latter is better adapted to the requirements of use where a neat and attractive screen is required. Or, for that matter the panels A, A, A may consist of solid slabs of wood or other suitable material where appearances or the admission of light are not essential.

In any case the panels are connected for use by means which admit of their being slid one upon the other. A preferred method of doing this is to provide the top and bottom edges of the central or basic panel A, with flange plates Z2, b, the inturned edges 6, b, of which form ways for the upper and lower edges of the auxiliary panels A, A, although it is obvious that the flanges on the main panel A, might be omitted and that similar flange plates might be attached to each of the auxiliary panels A, A with like result in that in either alternative the panels would be slidably connected the one to the other.

Set screws 0, 0, are provided upon the upper flange plate by means of which the panels may be secured rigidly together in prescribed positions with relation to each other, as after adjustment to the width of the window.

The panels thus secured together to form. a unitary screen structure foruse, are supported on and between side members of the window frame F, preferably by means of a.

right hand end bracket plate D, and a left hand end bracket plate D, each formed with centrally inturned flanges between whi h he and e g f the auxil y panels.

'A, A rest. The inner or rear flange cl, of each of these bracket plates is preferably inclined with relation to the vertical front flange (Z, thus facilitating the insertion of the ends of the screen and aifording an inclined back rest for the latter so that it will be supported at an angle with relation to the window sash 10, thereby deflecting air currents from the exterior upward into'the apartment to be ventilated through the space created by the raising of the sash was in Figs. '3, and 4. I

a By this construction and arrangement of:

arts I attain a verv simule and ineX en'sive ventilating screen for windows,-one that r is standardized as it were for general use and in a commercial sense, since it is applicable to all ordinary or average sizes of windows, is easily adjusted thereto, and is also of knockdown character in that it may be packed into small area for transportation or storage.

Gopies of this patent may be obtained for What I claim as my invention and desire to secure by Letters Patent is,

A ventilating screen comprislng acentral panel, and side panels, said central panel having a holding flange extending substan panel, thereby forming a continuous line with the edges of the 'sidepanels to provide an opening of continuous width between the assembled panel and thef window sash, a'j 'b111Cl1I1g"SCI'6W passing through each end of said holding flangeto bind against the side panels and hold them'in adjusted position,

and end brackets attachable to thewindow frameto hold the screen in outward'posi' tion.
